Embodiment Construction

[0037] The present invention will be further explained in detail below in conjunction with the accompanying drawings and specific embodiments, but it should be understood that the protection scope of the present invention is not limited by the specific embodiments.

[0038] The jacking equipment and construction method of tubular high-rise steel structure, the specific steps are:

[0039] (1) Component deepening and optimization

[0040] Detailed design steps: establish the overall model of the structure → assemble and segment on site (transportation segment) → process and manufacture segments → decompose into components and nodes → combine processes, materials, welds, structural design instructions, etc. → detailed design drawings.

[0041] (2) Selection of hoisting machinery

[0042] The steel structure should be all within the coverage of the tower crane 16, the hoisting height should not be too large, the weight of the segmented components should be within a certain range...

Abstract

The invention relates to an installation method of a tubular high-rise steel structure. The installation method comprises the following steps of S1 fixing a base; S2, constructing a bearing truss system; S3 installing a temporary support; S4, installing a limiting device; S5 lifting steel pipes; and S6 removing the fixed base, the truss system and the temporary support. The installation method solves the problem that a large-volume and large-tonnage steel structure is limited by the volume, the installation height and the installation environment of installation components.

Description

technical field [0001] The invention relates to an installation method of a tubular towering steel structure, in particular to a segmental jacking installation method of a large tubular towering steel structure. Background technique [0002] At present, the conventional method for high-altitude installation of large-scale steel structures is the full-room bracket method, which uses large-scale lifting equipment to hoist the parts and assemble them at high altitude. This method requires the installation of a large number of temporary support measures, the construction progress is slow, and at the same time it brings great safety hazards. Due to obstacles encountered at high altitudes, it is difficult to install large-scale hoisting equipment in place, and the components need to be divided into many units with small weight To meet the hoisting requirements, it brings a lot of high-altitude welding workload, the construction is quite troublesome and the quality is not easy to g...
